I rue the day I switched the desktops I manage to Ubuntu. I even
suggested recently in an IT staff meeting that we switch back to debian.
Didn't fly. The end users might like Ubuntu but it's a sysadmin nightmare.
Anyway, I like configuring my FAI system to look as much like a regular
install as possible. In a normal Ubuntu install, NetworkManager manages
the wired ethernet controller. But for years I have been struggling to
get NetworkManager to work after a FAI install. It simply would not
manage the primary network interface on a workstation after an fai
install. Turns out it's this bug:
https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/1658921
There is a file,
/usr/lib/NetworkManager/conf.d/10-globally-managed-devices.conf, that
disables management of wired ethernet controllers in NetworkManager. To
get it to work, you can just delete that file. But Ubuntu handles it by
createing a file, /etc/netplan/01-network-manager-all.yaml, that
re-enables it. So to get it to work in an FAI install, you can
configure FAI to either delete the file that disables NetworkManager or
install the file that re-enables it.
You also have to modify the stamdard FAI script, 30-interface, to *not*
configure the primary interface for ifupdown.
